Can't run a C# web API in Visual Studio 2022

Question

I am trying to run a web API written in C#,in Visual Studio code 2022 but I keep getting this error

An unhandled exception of type 'System.IO.FileNotFoundException' occurred in Unknown Module. Could not load file or assembly 'System.Runtime, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

Answer 1

I was having the exact same error, it turned out Visual Studio just needed an update.

Updated it and restarted the app and it went away.
